javascript - Javascript onmouseout 睡觉？

Question

在 Javascript 中，我希望我的 onmouseout 事件在生效前休眠/暂停/等待/（不确定此处的正确术语）三秒钟。这是如何实现的？

谢谢

Answer 1

function outfunction(event) {
    var that = this; // to be able to use this later.
    window.setTimeout(function() {
        …
    /* you can use 'that' here to refer to the element
       event is also available in this scope */
    }, 3000);
}

Answer 2

var doSomething = function () {
    //Some code will here after 3 seconds of mouseout
};

anElement.onmouseout = function () {
   setTimeout(doSomething, 3000);
};

上面的代码所做的是在被调用doSomething3 秒后执行函数onmouseout
